PEA-HULLER.

SPECIFICATION forming part of Letters Patent No. 561,616, dated June 9, 1896.

Application filed January 28,1896. Serial No. 577,145. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, JOHN M. SANDERS, a citizen of the United States, residing at Dalton, in the county of Whitfield and State of Georgia, have invented certain new and useful Improvements in Pea-Hullers; and I do hereby declare the following to be a f ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in pea-hnllers; and its object is to provide an improved construction of the same which shall possess superior results with respect' to eiiiciency in operation.

The invention consists in the novel construction and combination of parts hereinaf-- ter fully described and claimed.-

In the accompanying drawings, Figure l is a perspective view of a pea-huller constructed in accordance with my invention. Fig. 2 is a transverse section on the line m as, Fig. Fig. 3 is a central. longitudinal section of the same. Fig. ai is a perspective viewot` thc concave and its supporting-blocks.

In the said drawings, the referencemunieral l designates four uprights secured at the lower ends to transverse base-boards 2. These uprights are connected together' by lon gitu dinal bars 3 and a transverse bar a at one end and boards 5 at the opposite end.

The numeral 6 designates side boards forming with the said boards 5 a casing open at one end and provided at the upper end with a hopper 7, having` the upper portion flaring or inclined outward. This hopper is formed with inclined bottoni walls S and 9, the latter of which is formed or provided with a vertical wall l0. A space l2 is formed between the walls 8 and l0 for the passage of the peas to be hulled.

Located in the casing is a concave l3,forn1ed of a series of slats 14, secured to blocks l5, secured to the niachine-franie.- VThe concave on its innerside is provided with a series of rows of spirally-arranged teeth I6, which correspond with similar teeth 17 on the periphery7 of a drum lo. The drum is cylindrical and the concave extends about two-thirds around the same. Y At the inner end of the inclincd bottom is au inclined wall 1S, connected with an inclined chute l2), formed with an inclined extension 20.

The numeral2l designates an inclined tailboard pivoted at the inner end to the sides of the machine. At the outer end it is provided with a strap 23, formed with a number of holes 24, which engage with a pin and hold the board in any position to which it may be adjusted.

The numerals 2G and 27 designate two parallel inclined tail-boards, connected together with a space between, and pivoted at the inner ends to the machine-frame. The outer end of the board2'7has secured to ita bracket 28 provided with a number of'teeth 2Q, which engage with a stud or pin 30 and serve to hold the connected tail-boards in any position to which they may be adjusted. The object of adjusting the taibboards is to regulate the blast of the fan.

The numeral 3l designates a tairblower of any ordinary or suitable construction.

The numeral 32 designates the drum-shaft= provided at one end with a pinion 35, which meshes with a cog-wheel 3U on a transverse shaft 37, the opposite end of which is provided with an operating-crank Si and a fly-wheel or large pulley 3S, connected by a belt 88 with a small pulley 39 on the blower-shaft.

The operation is as follows: The peas are fed into the hopper and are caught between the teeth of the concave and drum and removed from the hulls or pods. The shelled or hnlled peas and thc pods or hulls then fall down into the chute, when the air-blast from the blower will blow them up on the tailboard 26, the hulls being blown out at the end of the machine, while the peas will fall into the receptacle at the bottom of the machine.

Any peas which may be carried up the board 2G will fall onto the board 27, and from thence will roll down into the receptacle.

By the above construction there will be no danger of the peas being crushed during the operation, and there will be no appreciable waste, as all the hulled peas will be carried down to the receptacle. This receptacle may be provided with a screen, if desired, to prevent the entrance of any trash or refuse.

Having thus fully described my invention, what I claim is- ICO 1 o tance of the chute from the drum een be regulated, of the pvoted teLboards at the lower part of the machine, the bracket secured to one of said tail-boards, provided with teeth and the pin with which seid teeth engage, substantially es described.

In testimony whereof I affix my signature in presence oftwo Witnesses.

JOHN M. SANDERS.
